Quick and dirty In Theaters column this week.  Mission Impossible: Fallout returned us to our winning ways.  Fallout took in a franchise record $61.3 million to handily take the weekend crown last week over #2 Mama Mia: Here We Go Again, which managed $15.2 million.  This weekend brings three new wide releases: Disney’s Christopher Robin, Kate McKinnon’s comedy The Spy Who Loved Me, and the critically-acclaimed Eighth Grade.  This weekend’s box office race will be between Fallout in its sophomore week and Christopher Robin.  Right now, looking at it, I think Fallout will be able to hang on due to repeat business and its crazy good reviews pulling in people who normally wouldn’t see a Mission Impossible film in the theater.  Looks like it will be really, really close.
